SCYTHE-SNATHE COUPLING-.-

To all whom t may concern Be it known that I, JOHN K. CHAMP, a citizen of the United States, residing at Paris, in the county of Bourbon and State of Kentucky, have invented certain new and useful Improvements in Seythe-Snathe Couplings, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in Scythe snathe couplings and the object of the invention is to provide a device of this general character having means of a novel and improved character whereby the scythe may readily Vand conveniently be adjusted relatively to the snathe as the requirements of practice may dictate.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be earfully defined in the appended claim.

In order that my invention may be the better understood, I will now proceed tordescribe the same with reference to the accompanying drawings, wherein Figure 1 is a fragmentary sectional view taken through a coupling constructed in accordance with my invention; Fig. 2 is a fragmentary top plan view of the device, as illustrated in Fig. 1, with parts being shown in section; Fig. 3 is a view in bottom plan of the heel portion of the Scythe, as herein disclosed; Fig. 4 is a sectional view somewhat similar to Fig. 1 but illustrating a further embodiment of my invention; and Fig. 5 is a view in bottom plan of the part carried by the snathe, as disclosed in Fig. 1.

As disclosed in the accompanying drawings, 1 denotes the snathe which may -be as desired, while 2 represents lthe Scythe provided with the heel portion 3 directedsubstantially at right angles to the scythe proper and having its outer or free extremity provided with the segmental rack 4: adapted to mesh with a similar rack 5 produced on the socket or band member 6 adapted to be suitably secured to the lower end portion of the snathe in any manner desired, but, as herein shown through the me Specification of Letters Patent.

dium of the bolts 7 and coacting nuts or burs 8.

The socket member 6 is provided, as herein disclosed, with the forwardly directed arm 9 adapted to be disposed substantially parallel with the heel 3 of the scythe and adjacent its outer or free extremity such arm 9 is provided with the depending lug or finger 10 circular in cross section which is adapted to project within a suitable opening or aperture 11 produced in the heel 3 adjacent its junction with the scythe 2 and serving as a pivot whereby the Scythe may have movement relatively to the snathe to control its angle. To maintain the Scythe in its adjustment and to prevent the racks 4 and 5 from becoming disengaged the arm 9 in advance of the rack 5 is provided with a perforation 12 adapted to register with a segmental slot 14 produced in the heel 3 in close proximity to and in advance of the rack 4 and through which is adapted to pass the clamping` member 15, herein shown as a threaded bolt adapted to be engaged by the nut or bur 16 whereby the arm 9 and heel 3 may be readily and effectively held in desired operative relation. I also find it of advantage to have the upper face of the heel 3 surrounding the slot 14 depressed to afford a segmental groove 17 against which the flat faces of the head 13 of the bolt 15 are adapted to contact to prevent axial movement of said bolt as would otherwise have a tendency to become loosened from its clamping nut or bur 16. I have also found in practice that good results can be obtained by reversing the arrangement of the parts as herein set forth and wherein the heel 3 adjacent its free or outer extremity is provided with an upstanding lug or projection 19 adapted to be accommodated within a suitable perforation 2() in the arm 9 of the socket member 6, as is particularly shown in Fig. L1.

From the foregoing description, it is thought to be obvious that a scythe snathe coupling constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which the scythe may be maintained in its adj ustments relatively to the snathe and it will also be obvious that my invention is susceptible of some change and modification Without material departure from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to the precise arrangement arid formation of the several parts herein shown in carrying out my invention in practice.

I claim:

In combination, a Scythe provided with a heel having a segmental rack produced on the upper face thereof, a socket member Scythe, the lower end of the socket member being provided with a segmental rack to mesh with the rack of the heel= means coacting With Ithe arm of the socket and heel of the scythe to aord a pivotal connection therebetween, and a clamping means coacting with such arm and heel for maintaining the racks in mesh.

In testimony whereof I hereunto aix my signature in the presenceV of two Witnesses. JOHN ILCHA-MP. lVitnesses j GEORGE BixLLEirrox, W. M. BYARS.
